But a debate among lawmakers today on whether to ban Trump from the country revealed that there's little support for that idea.

During the three-hour debate, legislators from Britain's main parties stood to call Trump an attention-seeker, a demagogue and a fool. Many, though, argued that he should not be stifled or banned.

Labour Party legislator Paul Flynn, who opened the session, said Trump had already received "far too much attention."

Parliament took up the topic after half a million people signed a petition calling for Trump to be excluded over his call for a temporary ban on Muslims entering the United States in the wake of extremist violence. Trump has also claimed that some areas of Britain are so radicalized that police fear for their lives.

Under British law, any petition supported by 100,000 people - who must each provide and confirm an email address - is considered for parliamentary debate.
